Abstract
The present invention discloses a flat transmission multi-mode resonant cavity. The flat transmission multi-mode resonant cavity includes at least one cavity capable of exciting two or more working modes and a coupling structure. When an electric field is provided in the cavity In the case of a metal body, a microwave absorber is also provided on the upper cover plate of the cavity directly above the electric field metal body, and a microwave absorber is provided on the surface or inside of the microwave absorber. When the electric field metal body is not arranged in the cavity, the microwave absorber is arranged at the electric field concentration of a certain working mode in the cavity. By improving the prior art, the present invention overcomes the defects in the prior art, and makes the in-band fluctuation of the multi-mode resonant cavity flat. The present invention belongs to a kind of filter technology, which is mainly used in electronic systems of various microwave bands, especially in the fields of radar, communication, missile guidance and the like.
